Which parameter is NOT part of the Britter-McQuaid correlation methodology?

The Britter-McQuaid correlation methodology is a widely recognized approach used to model the dispersion of contaminants in the atmosphere. The model relies on several key parameters, including wind speed, source strength, and atmospheric stability, as they are essential for predicting how pollutants disperse over distances.

Wind speed is a critical factor in determining how quickly and in what direction a contaminant disperses. Higher wind speeds generally lead to greater dispersion, as they carry contaminants away from the source more rapidly.

Source strength refers to the amount of pollutants emitted from a source, which directly influences concentration levels in the air. Understanding the source strength is crucial for accurately estimating the resulting dispersion pattern.

Atmospheric stability is another vital parameter, as it describes the vertical mixing of air. Stable conditions can trap pollutants closer to the ground, while unstable conditions can enhance vertical mixing and promote dispersion.

Since wind speed, source strength, and atmospheric stability are all integral components of the Britter-McQuaid methodology, indicating that they are NOT part of this model would be incorrect. Therefore, the choice that states "All of the above" as not being part of the methodology is the right selection, since it misrepresents the foundational elements that are, in fact, essential for this correlation
